Abstract
A process is disclosed in which a spent mixed anion/cation exchange resin bed is hydraulically separated into cation, anion and interface resin cuts. The interface resin cut is further classified by various physical separation techniques. Cation and anion resins are separately chemically regenerated. In an alternative embodiment cation resin fines are physically separated from the anion resin cut.
